There were some dates when all of the trades were buys. There were at most a handful of dates when selling above $.002 was possible. If you check the highs and lows for most days, the spread was huge.
This afternoon the ask dropped to $.0015, which stimulated little buying. At least the spread became tighter.
There is just not much demand for MDGC stock. Considering the large float, the average volume is miniscule.
